Different year-end for two scenarios within the same FCC application

Question:

What are possible approaches in FCC to handle different year-end for two scenarios within the same application?

Background:

The application is set for a Jan to Dec (with 13 period) or P1 to P13. The main Actual scenario is fed with true GL data with a Dec year-end. There is however the need to consolidate and report specific data for entities with a Jun year-end, i.e. a different Actual_xx scenario in the same FCC application. Jul is therefore the first period ("P1") and not Jan.

I understand that the start and end periods in FCC is set once and will be applied to all scenarios.
